“This issue is fixed in app10 UPD 16.
In UPD 14 & 15 you will not see finished work tasks in the LOV ( of the posting proposal window) , but you can manually add the WT number without any error . In UPD 16, it is not even possible to add a finished work task manually, it will pop up an error message when you try to save the record.”
Has this logic been changed in IFS Cloud? (We are currently running 24R1 SU6)
In the screenshot below our Finance Lead created a posting from a manual supplier invoice towards a Finished Work Task without the expected error message.

We have several companies in the same environment, and some of them would like an error message for this scenario, and others likes that the system allows this.
Are there any planned changes for this functionality in 25R1 & 25R2?
